This invention relates to a smoke ring emitting or discharging device particularly adaptedto be used in toy gunswhich is novel and inexpensiveto make and it isan ob1ect of the invention to provide such a dev1ce adapted to emit or discharge perfect rings of smoke at any desired interval of time.

Further objects of the invention will hereinafter appear.

The invention embodies a tubular member in simulation of a gun barrel, closed at one end and arranged with a bore having difi'erent diameters, with the portion of smaller diameter at the outlet or discharge end thereof; or itmay havea bore of uniform diameter and arranged at the outlet end thereof with a restricted portion adapted to form smoke emitted therefrom into smoke rings. The smoke is generated in a carrier releasably mounted on and; in commun cation with the tubular member, enters into said member and is emitted through the outlet by impulsesof air created at and within the closed end of the tubular, member by means actuated exteriorly of the tubular member by an intermittent moving member which may be controlled by a trigger or the like.

In the drawing accompanying and form'- ing a part of this application, Figure 1 is an elevational view of the device partly in section to show the manner of restricting the bore of the tubular member and'the air impulse creating means and actuating means therefor- Figure 2 is a plan View looking at the top of Figure 1.

Figure 3 is an enlarged view looking at the rear of Figure 1, partly broken away to show the air impulse creating means.

Figure 4 is a perspective view of the car-' of a casting having a bore of uniform diam eter or of irregular diameter with the portion of smaller diameter adjacent the outlet end, as illustrated in the drawing, adapted to be, pivotally supported upon; standards 7 in the form of a figure A, by trunnions 8 fixed to and extending laterally from. the

tubular member and pivotally engaging 12 havingan open top 13 curved to conform to the per phery of the tubular member for the mountlng of the receptacle on the underside of the tubular member adjacent ;the

closed end thereof in communication with a perforation 16 therein to permit the smoke from the incense to enter the tubular inemberf-and to prevent the escape of any smoke fromthe receptacle. The receptacle is socured to the tubular member by. an extended portion or flange 14 integral with the receptacle extendingin a plane with'the top of the receptacle and also curved to conform to the periphery of the barrel and arranged H with a slot 15eXtended in from the end thereof to slidably engage a button orheaded pin '17 fixed to 'and extending laterally of the tubular-member. The receptacle is arranged with a hand grlp 18 at the end opposite the I Figure 4, carried in a rectangular receptacle i end with the flange 14 tomanipulate the receptacle on the tubular member to change or renew the fumid material. 1

To expel the smoke accumulated in the tubular member from the carrier 12 and cause the emitted smoke to form rings, the

bore of the tubular member may be arranged with two different diameters forming two different sized. chambers, the smaller cham ber 19 being arranged at the discharge or outlet end and the larger chamber 20 at the closed end and arrangedJwiththe perform tion 16 for the admission thereto of the smoke generated intllecarrier'l2; or the tubular member mayjbe arranged with an uniform formed by the forcing of the smoke from the larger chamber 20, or the portion of the tubular member in the rear of the annular abutment, through the smaller. chamber 19 or annular abutment 21 by creating air impulses at the closed end of the tubular member by exerting air compressing force on the rear of the smoke in the tubular member and the sudden relief of the compressing force in the discharge of the smoke "from the outlet end of the tubular member.

The air impulses forforcing the smoke into the smaller chamber 19 or through the abutment 21, and emit the same from the outlet are created by a plunger comprising a disk 22 of flexible material carriedby a rod 23 slidably mounted in the head of a cylinder 24 inserted in the open end of the chamber and which serves toclose said end and secured therein bya flange extending radially of the head and abutting the edge of the tubular member. The disk is maintained in abutting relation to said head by a coiled spring 25 of conical form confined betweenthe exterior of the head of the cylinder and aknob 26 on the rod 23-. The head of the cylinder is arranged with, a Pe t n to P rmit o th escap of the air between the disk and head, and the diskto assume the abutting relation thereof with the cylinder head.

The plunger is moved into the cylinder against the actien of the spring tocreate mpu s o a r in the ubular mem er by a reciprocating member in the form of a bar 28 vot lly S pp ted. at on nd n a Pi 29 'nxed to'a side wall of a casing- 30 mounted n a d, e te d ng b kw rd q the am 20 of the'tubular member, with the opposite end of the bar arranged with a lateral extending finger or ha mmer 31 for contact with the lrnob. 260i the plunger, and intermediate he e of the bar; p v y c e by the bar there is provided a pawl 32 adapted to be limited in, one direction of movement thereof by a detent 33extending from an edge of the bar adjacent the. mountin of the pawl and to be. engaged by a rotatab e. cam member to reciprocate. the bar 28. in one direction of rotation thereof.

The cam member comprises disk 32 carrying pinsv 35, twoin. number inthe present instance for the engagement with the pawl 32 and fixed on a shaft 36 extending transversely of the. casing and rotatably mounted in the side walls. thereof adapted to. be rotated by the unwindingv of a coiled; clock spring 37 fixedv at one end to the shaft and the opposite end fixedto a pin; 38 projecting from a wall of the casing opposite the wall carrying the pin 29. The spring is tightened or woundup by the rotation of the shaft by a key 39 fixed to a portion of the shaft extending exteriorly of the casing. Upon the rotation of the shaft to wind up the spring the disk 34 is rotated positioning the pins into engagement with the pawl 32 rotating the same and permitting the pins 35 to pass and the rotation of the disk without imparting movement to the bar, and during the unwinding of the spring the disk is rotated in the opposite direction when the pins engage the pawl 32 moving the same against the detent 33 imparting forward movement to. the bar forcing the hammer against the knob 26 and moving the plunger into the cylinder and creating air impulses in the tubular member.

To control the reciprocation of the bar 28 and the plunger, va trigger 40 is pivotally mounted at one end on the casing wall carrying the pin 38 and arranged with a detent ll to engage a ratchet wheel 42 fixed to the shaft '36'to stop the rotation of the shaft in the spring unwinding direction of rotation,

the trigger being influenced to, engage the detent with the ratchet wheel by a spring 42, one end thereof fixed to the proximate casing wall and other, end fixed t0 the trigger to permit the rotation of the ratchet wheel during the winding of the spring 37. The

trigger is arranged with a finger cngaging portion as extending beyond the casing adjacent a recess 4i formed'in the casing. The upper edge of the casing is open tofacilitate the inspection and replaeementof the actuat ng' mechan sm housed there n and 1t 1s PlOYldQCLVVLlill a cover 45 of flex ble material engaging grooves, in the edges of the casing opening and secured tliereto and also forming the butt of the gun.

It will be obvious that various modifications may be made in construction and arrangement of parts, and that various. means other than that illustrated and described may be utilized to create the smoke emitting air impulses, without departing from the scope of the. invention.
